Title: Sheet taking-out and supplying method, sheet taking-out and carrying part and sheet taking-out and supplying device
Inventor: TOMOTAKI TAKAMICHI
IPC: G02F1/13
Filed: 1995-03-08
Abstract: PURPOSE: To prevent the surface of a thin sheet from being damaged by contact, to prevent trace by friction from being left on the surface of the sheet, and further to exactly take out and carry the sheet one by one even when it is curled in the case of taking out and carrying the thin sheet which is easily damaged by synchronizing the carrying speed of the sheet with the circumferential speed of a carrying roller. CONSTITUTION: When a driving motor 17 is actuated in a state where only the sheet in the uppermost layer is surely attracted by an attraction part 7, a rear attraction part 8 and a holding plate 9, the attraction parts 7 and 8 and the plate 9 advance and the leading edge of the attraction part 7 gets into the recessed groove 2a of the carrying roller 2. Since the leading edge of the sheet is inserted and bitten between the roller 2 and a pinch roller 3 before the advancing limit of the attraction part 7, the circumferential speed of the roller 2 is controlled in accordance with the change of the speed of the sheet. Thus, in the case the sheet is bitten between the rollers 2 and 3, slip does not occur between the upper surface of the sheet and the roller 2, and the lower surface of the sheet and the roller 3, the sheet is transferred without leaving the trace by the slip.

Abstract: PURPOSE: To make a shape of glass plate having a uniform rate of curvature and protect an operator against the danger by a method wherein a rotating axis of a grinder head is displaced by a rotatable sleeve and the grinder head for grinding a glass plate is oscilated by a rotary shaft rotatably supported.  
     CONSTITUTION: Rotating axis 21 fixed to the grinder head 23 is rotatably supported at such a position as being eccentric with respect to a rotating axis of the sleeve 18 itself in the rotary sleeve 18. When the corner of the glass plate 1 to be ground is positioned such that it is placed at a center of rotation O of the rotary sleeve 18, a center of the rotary grinder 26 is placed at a point A and the rotating axis 21 of the grinder head 23 is positioned at the point 21' directed in a lower leftward direction by 45°. Thus, a rotation of the sleeve 18 causes the rotating axis 21 to be moved in sequence of 21'→21"→21'''→21', then a center of the grinder wheel 26 is moved in an arcular path A→B→C→D→A, thereby the glass plate is contacted, ground to make an arcular corner and then removed. Thereby, it is possible to provide a grinding of the glass plate having corners with uniform rate of curvature without causing any danger.

Title: Superconducting transformer
Inventor: FUJIWARA YASUO
IPC: H01F36/00
Filed: 1988-03-30
Abstract: PURPOSE:To reduce adjustment required for compensating difference in dimensional changes of respective members due to strengthening of a cryo vessel or very low temperature by a method wherein high tension coils and low tension coils are located so that they face each other at two or more points. CONSTITUTION:Low tension coils 41, 42 are located at both ends and high tension coils 31, 32 are located at the center, where a high and a low tension coils 3, 4 face each other at two points. A large current directing toward 8 flows in the high and low tension coils 3, 4 when a circuit is shorted on a load side, resulting in generation of large electromagnetic force in the direction of arrows 10 which repulse each other. However, if the low tension coils 41, 42 are equally divided into two, the electromagnetic force is equal with respect to high tension coils 31, 32, so that both are offset inside and no force comes out. This reduces adjustment against change in member dimensions due to very low temperature and strengthening a cryo vessel 2 for the purpose of resisting short-circuited electromagnetic force.
